Record-Breaking Summer Heat Raises Health Concerns For Older Adults

We sweat less as we age, which slows the ability to cool down. We also become less sensitive to thirst, so we can already be dehydrated by the time we're thirsty.

This summer's heat has been breaking records. It's also been raising health concerns for groups vulnerable to extreme heat.

As Haley Ott reports, health officials are specifically concerned about the heat's impact on older adults.

Doctors stress keeping the elderly cool and safe when temps are soaring is critical to avoid heat-related illnesses.

Older adults may not be able to notice the heat and adapt to it, according to geriatric specialists at Rush University Medical Center.

We sweat less as we age, which slows the ability to cool down. We also become less sensitive to thirst, so we can already be dehydrated by the time we're thirsty.

Common conditions in the elderly can make it harder to adjust to rising temperatures. Patients with diabetes, kidney disease, dementia, and depression can experience dehydration more easily.

Some medications also make it harder to stay hydrated.

On these hot days, older adults should keep water by their side. Avoid drinks with caffeine, sugar or alcohol. Set a timer to remind to drink water.

Keep a close eye on the temps inside as well as outside. Try to keep your home between 68 and 78 degrees.

If you have older loved ones or neighbors, be sure to check on them. Weakness and confusion are symptoms of heat exhaustion.
